To all whom t may concern.'

Be it known that I, GEORGE LANE, a citizen of the United States, residing at Poughkeepsie, New York, have invented certain new and useful Improvements.y in Lifting- Jacks, of which the following lis a spccifcation, this application being a continuation .of an application filed by me on the 11th .spring action one Way to eliminate the oonstant urging of the handle backward by the spring and the consequent tendency of its getting into an intermediate position, and further to provide a construction which will compensate for commercial variations and render unnecessary alterations 1n the jack.l

A still further object is to provide a construction with an extremely slmple form of folding handle which will be of maximum strength and rigidityiwhen in use, andv in which the reversal of-'the jack may beeffected by a pushror pull upon the outer end of the handle bar. i

With these and other objects in view the invention includes the novel featuresof construction and arrangement and combination of parts hereinafter described, my said invention being defined by the appended claims.

An embodiment of the invention is illustrated in the accompanying drawing, in which,

Figure 1 is a sectional elevation of a sufi-i1 cient portion of a jack to illustrate my irlvention.

Fig. 2 is a cross section through the actuating lever with the handle bar in place.

Fig. 3 is a longitudinal section through the handle bar, and,

Fig. 4 is a plan View of the same.

Referring by reference ohara eters to these drawings, the standard 2, lifting bar Band retaining dogs being connected by the springs 14 and 13 with the bell crank levers 12 vand 11 mounted alongside the actuating lever 6, and having their contact portions pressed toward each other by a' common spring C,

Actuating lever 6 is provided with a socket to receive a handle bar of material length to enable the jack to be placed inl position without crawling under the car, which handle is. made folding' to enable it to be conveniently placed in the'V tool' boxnd retained in the socket by a spring To effect the reversal of the jack I .prof

vide a shiftable contact pin orcontroller b,

which is designed in one position (shown in full lines in Fig. 1) to contact with the bell crank levers alternately as the actuating lever is operated, and thus effect the lowering of the lifting bar, while in another position thc pin or contact portion lies be? yond the range of Said bell crank levers, as shown in dotted lines at b in Fignl, whereby the pawls 4 vand 5 operate to eifect `the step by step raising of the lifting bar.

This pin or controller is caried on a thin stripof sheet metal 8X slida ly carried on the side of the forward portion handle bar 7X. The" aggregate thickness of the end of the handle bar and the metal strip is such as to enable it to be inserted in the socket of the actuating lever, as shown in Fig. 2. The thin or controller actuating strip is held to the side of the handle bar by the con-trolling pin at its front end which passes through an elongated slot w in the front end of the handle bar, and at its rear end a rvetl 20 which passes through a slot w in the handle bar. The handle bar is composed of two sections 7 x and 7y pivotally connected to. gather by the rivet 20 above referred to, and to lock them together in front of rivet 20, a pin 21 is ada ted to pass through the slot m in the hand e bar portion 7", and an alining recess in the section 75'.-

A chain or other flexible cbnnection may be provided-for attaching the pin 21 to the. handle bar to prevent loss removed for folding. y

of the pin when,

.55 as in my aforesaid patent, the lifting andi` 1With the handle bei* 1n place es Shown in Fig. l a pull upon the-handle Der Section IY moves the pin or controller to its enten. moet :position shown in Fig'. i. in dotted linee sets 'the jack 'for inising, while :t push upon seid section Ty moves the pin or controller forwerd into the position shown in full lines Fig. l and sets the iack for lowering.

Having thus vdescribed my invention, what l. A jack comprising e standard, elifting bar, lifting and retaining pawls, e lever mounted in nthe standard having e socket for reccivinglan operating bar, devices cerried by the standard for controlling the op-l eration of the pawls, a handle bar having an end adapted to be he'ld in the socket, and e ehiftwble member carried by 'seid operating ber having a, controller to actdirectly upon said devices movable into end out of actuef ing position in reference to said `devices.

2. A jack comprising a standard, e lifting bnr, lifting and reteiningpawvls, an actuating lever mounted in the standard having e eoclset 'for receiving an operating bar, deyices carried 'by the standard for controlling the operetion of the pewls, an operating bei' limiting en end adapted to be held in the socket, seid operating bar comprising two niiembers connected together to lieve relative sliding movement, zt'sliifteble member cerried by the innermost member and connected to be oper/eind bv the outermost member and' e controller connected to said Shiteble inembei1 yto ect directly upon seid devices.

3. A jack comprising e standard, li'ting bm?, lifting and retaining puwls, en eci/neting lever mounted in the standard having e.V socket for receiving en operating ber, de-

vices cerried by the standard for controlling member, a controller connected to said shifta'ble memberA end releasable means for locking seid members of the operating bei' inv alinement 4. A 1' ack comprising e stendardi, a lifting loer,- liiting and retaining parvis, e lever mountefl in the standard having a socket for receiving `en,opere-ting lber, devices cerried by the stende-rd 'for controlling the operation of the pawls, a handle bei' having an end. adapted to be held in the socket, a, thin flat sheetJ metalli-er slidebly held to one side of seid handle bei, and a .laterally `extending controller carried by seid sheet metal bnr end acting directly upon the seid devices,

In testimony whereof, I alix my signeture. t
